TIME-S WITCH.

Specification of Letters Patent.

Patented Jan. 3, 1911.

To all whom it may concern:

Be it. known that l, A mnon \V. Kolnun, a citizen of the United States,residing at Richmond, in the county of l-lenrico and State of, Virginia,have invented certain new and useful improvements in Time-Switches,

of whiclrthe following a. specification,

reference being had to the accompanying drawings.

This invention relates to improvements in time switches, and moreparticularly a time controlled electrical cut out adapted for use instores and buildings for extinguishing one or more. electric lamps orseries of lamps at.- a predetermined time, although the device may beemployed for other purposes.

' The object of the invention is to provide an improved cut-out orswitch of simple and practical construction which may be conyenientlysetand when set will be entirely automatic in operation.

- \Vitli the. above andjother objects'in view,

the invention consists of the novel features a of construction and thecombination and arrangement of parts hereinafter fully de scribed andclaimed and illustrated in the accompanying drawings, in which--.Figure'l is a front/eievation'of my: im-

7 proved time switch, the electric-circuit being diagrammaticallyillustrated." Fig. 2 is a de-v tail sectic' nal View taken on the planeindicated by "the line 2+2 in Fig. l,and-'Figs. 3

.J'and tare detail views of parts; Referring moreyparticularly to-thedraws "ing,-1 -indicates a-clock dial upon. which my improved Qti meswitch'is arranged. This switch is controlled by the hour hand 2 of theclock which carries a trip pin 3, V which is' fa'dapted toiengage andactuate acou- -ductorgarm, l, pivotally mounted to rotate I aboilljt thehour;handshaft 5 from which it:

"conductor-amid is thus mounted for movei Inent independent of thetime"indicating hands ,and'itdsfadapted to be adjusted to break theelectric circuit-at a predetermined -A cont-actbloclti -is arranged formove;-

Im'entbetween the concentric stationary nonconductin rings 8 whichare-secllredupon thetacc o .the-dialin"any well known man insulatingmaterial; The rings Bfare'of angu- 'lart os'issecti'onali:forniltopifoyide'the track the opposite edges of the contactblock 7. It will be noted from reference to Fig. 2 of the drawing thatthe flanges 9 of these rings are slightly inclined, the flange of theinner ring being disposed nearest the face of the clock dial. The upperand lower surfaces of the contact block 7 when in position between theflanges 9 are therefore also inclined toward the center of the dial. Theblock 7 is formed 'in two sections, one of which is composed of copperor other electric conducting material, and the other of rubber or anywell known insulation as indicated at 7'. These block sections may becemented or otherwise secured together, and the metallic section isprovided with a suitable finger piece as shown at Fig. 3 whereby theblock may beeasily moved between the concentric insulation rings 8, toany desired point of the clock dial, at which time it is desired tobreak the circuit and extinguish the lights. The end of the arm 4: isthen positionedupon the upperinclined surface of the block 7.-

This arm is .sufliciently resilient to cause 'the same to retain itsposition upon the block 7 in any position of the clock. The sleeve 6upon which the innerendof the arm 4 is mounted is fitted upon the shaft5 so as to prevent outwardmovementof the arm toward thegcasing of thedial whereby secure frictional'contact'of tl1e end of the arm, with 'theblock 7 after it is released is insured.

After-the block has been properly positioned andthe arm engagedtherewith, the circuit is connected, and when the hour hand 2 reachesthe t-imeset for extinguishing the flights, the pin 3 carried therebyengages thearm 1 and moves the same from the timing section of the blockto .the insulated section 7, thereof, thereby breaking the circult, andthe said arm 4 continues tomove withthe hand until itclears theinsulated section offthe block and drops 'therefrom upon the noneonducting rings s:. .By providing the, insulation .section 7-, in the ventthat'the arm 1 should drop back a-gainstthe endof the block," thecircuit would Istilllbe disconnectedQ-The conducting wires grand 1210fthe circuit are connected-to 'theinner endof theiarinfl, and to'themetallic section of the block :7 respectively; The lamps 13 areincludedin the circuittogetherwith a cut out ,switchl. One "ormoreoffi-saidswitches may be mounted on a panel, board controlling thefsygitches I "14,. illldaihcitliiing no 15, which is pr'oyided. with amain; switch 16,

an electric circuit 17 containing a meter 18, which is connected toasource of current supply by means oft-he wires 19, which latter may bethe usual street line of an electric light company supplying the currentto the buildin 1n which the switch is arranged. \Vhile t llS is onemanner in which the switch may be connected up and used, it will. beobvious that the invention may be utilized in many other ways and for agreat number of different purposes. The circuit wire 17 need notnecessarily ass through the casing which incloses the c ock and switchmechanism, when connected in series before switch 16., Furthermore, itwill, be readily understood that the wire 12 may be directly connected'to the circuit wires-17 andthe con' trolling switches 14 and 16located at a point distant from-the time switch when all lights aresimultaneously extinguished.

-ln the use of the invention, as above 'stated, tl1e block. is moved tothe desiredpoint and the resilient arm 1- lifted and disposed upon thesame. At the proper time, the 'pin 3 engages said. arm and moves thesame ofl of the block 7 and breaks the cit cuit and extinguishes t-helights. 'After the arm movesofl-of the block, the resiliency of the samecauses it to engage upon the flanges 9b)? the non-conductin rings whereby itis disposed below the en of'the pin 3,

thus remaining stationary while the hour hand 2 continues its-movement.The'arm 4 is also, providedwith a finger piece similar to that-carriedby the block .-7 whereby, it'may be readily lifted and engaged uponthe.-con-' tact' member. stood that when the block" and arm 4' have"been properl adjusted, th e switches 1 and '16 are close so thattheelectric circuit is connected. It will beunderstood that in practicethe handles on the block 7 and on the conducting arm 4 will be madeofinsu latingmateriai so as to render it safe tohandle the "device. Itwill also be. understood-that should it become necessary, suitablemeans-will be-provided to hold the construction and 0 block 7 thevarious parts, itwill be understood that It will of course be under--'against movement between the.

the device is susceptible of many minor shaft, a conducting blockmovable between the said guide rings and pro ecting from the outer facesthereof, hands on the hand shaft, one of the said hands being providedwith a pin which projects toward the dial and a conducting arm'pivotally mounted on the hand shaft and for disposition with its .outerend on the said' conducting block to dispose the said conducting arm inthe path of the said pin of the said hand, the said conducting arm beinga spring arm and adapted thereby when moved from the said conductinblock to move out of the path of the said pin.

.2. In apparatus of the class described in' combination with a clockdial having a pair of concentrically disposed non-conducting rings onthe outer side thereof, spaced apart and provided on their opposingsides with flanges, a conducting block mounted for movement between thesaid guide rings and having grooves in its sides engaged by thefiangesthereof, said conducting block projecting beyondthe outer sides of saidguide rings and being also provided with a noneonducting section at oneend thereof, a hand shaft projecting from the dial, hands on the handshaft, one of thesaid hands being provided with a pin whiclrprojectstoward the Y dial, and a spring conducting arm mounted on the said handshaft for movement aroundthe dial, and to bear-on the said block, the

said conducting arm when thus'disposed on the block being in the path ofthe said pin of the said hand, the said conducting arm when moved fromthe said block dropping upon the inner guide ring, and hence getting outof the path of the said pin'forthe purpose set forth.

In testimony whereof I hereunto aflix my signatnrein the presence of twowitnesses. ARTHUR W. KOINER.
